Extracorporeal membrane oxygenation in obstetric patients: An Israeli nationwide study.

BACKGROUND: The leading causes of maternal mortality include respiratory failure, cardiovascular events, infections, and hemorrhages. The use of extracorporeal membrane oxygenation (ECMO) as rescue therapy in the peripartum period for cardiopulmonary failure is expanding in critical care medicine. METHODS: This retrospective observational study was conducted on a nationwide cohort in Israel. During the 3-year period, between September 1, 2019, and August 31, 2022, all women in the peripartum period who had been supported by ECMO for respiratory or circulatory failure at 10 large Israeli hospitals were identified. Indications for ECMO, maternal and neonatal outcomes, details of ECMO support, and complications were collected. RESULTS: During the 3-year study period, in Israel, there were 540 234 live births, and 28 obstetric patients were supported by ECMO, with an incidence of 5.2 cases per 100 000 or 1 case per 19 000 births (when excluding patients with COVID-19, the incidence will be 2.5 cases per 100 000 births). Of these, 25 were during the postpartum period, of which 16 (64%) were connected in the PPD1, and 3 were during pregnancy. Eighteen patients (64.3%) were supported by V-V ECMO, 9 (32.1%) by V-A ECMO, and one (3.6%) by a VV-A configuration. Hypoxic respiratory failure (ARDS) was the most common indication for ECMO, observed in 21 patients (75%). COVID-19 was the cause of ARDS in 15 (53.7%) patients. The indications for the V-A configuration were cardiomyopathy (3 patients), amniotic fluid embolism (2 patients), sepsis, and pulmonary hypertension. The maternal and fetal survival rates were 89.3% (n = 25) and 100% (n = 28). The average ECMO duration was 17.6 ± 18.6 days and the ICU stay was 29.8 ± 23.8 days. Major bleeding complications requiring surgical intervention were observed in one patient. CONCLUSIONS: The incidence of using ECMO in the peripartum period is low. The maternal and neonatal survival rates in patients treated with ECMO are high. These results show that ECMO remains an important treatment option for obstetric patients with respiratory and/or cardiopulmonary failure.

Considerable paediatric drug dispensing - A nationwide study of more than 2 million Swedish children.

AIM: The aim of the nationwide study was to describe paediatric drug utilisation in Sweden. METHODS: Drug prescriptions dispensed to all children aged 0-17 years in 2019 were analysed using data from the Swedish National Prescribed Drug Register. RESULTS: We retrieved data on 2 180 508 unique children. Nearly 4.6 million prescriptions were dispensed to children aged 0-17 years, and 52% of these were to boys. Just under half of the children (47%) were dispensed at least one drug: 48% of girls and 45% of boys (p < 0.01). More than a third (34%) were dispensed three or more different drugs during 2019. The number of dispensed prescriptions per 1000 children was higher in boys than girls up to 12 years of age (p < 0.01), and the opposite trend was observed from 13 years and above, even when we excluded contraceptives (p < 0.01). The most common therapeutic areas were drugs for the respiratory tract (25%), namely antihistamines, antiasthmatics and cough medication. These were followed by psychoanaleptics and melatonin for the nervous system (19%) and dermatologicals (16%), namely cortisone creams and emollients. CONCLUSION: Paediatric drug use was common, and a considerable proportion of children were dispensed multiple drugs.

Clinical implementation of partial oral treatment in infective endocarditis: the Danish POETry study.

BACKGROUND AND AIMS: In the Partial Oral Treatment of Endocarditis (POET) trial, stabilized patients with left-sided infective endocarditis (IE) were randomized to oral step-down antibiotic therapy (PO) or conventional continued intravenous antibiotic treatment (IV), showing non-inferiority after 6 months. In this study, the first guideline-driven clinical implementation of the oral step-down POET regimen was examined. METHODS: Patients with IE, caused by Staphylococcus aureus, Enterococcus faecalis, Streptococcus spp. or coagulase-negative staphylococci diagnosed between May 2019 and December 2020 were possible candidates for initiation of oral step-down antibiotic therapy, at the discretion of the treating physician. The composite primary outcome in patients finalizing antibiotic treatment consisted of embolic events, unplanned cardiac surgery, relapse of bacteraemia and all-cause mortality within 6 months. RESULTS: A total of 562 patients [median age 74 years (IQR, interquartile range, 65-80), 70% males] with IE were possible candidates; PO was given to 240 (43%) patients and IV to 322 (57%) patients. More patients in the IV group had IE caused by S. aureus, or had an intra-cardiac abscess, or a pacemaker and more were surgically treated. The primary outcome occurred in 30 (13%) patients in the PO group and in 59 (18%) patients in the IV group (P = .051); in the PO group, 20 (8%) patients died vs. 46 (14%) patients in the IV group (P = .024). PO-treated patients had a shorter median length of stay [PO 24 days (IQR 17-36) vs. IV 43 days (IQR 32-51), P < .001]. CONCLUSIONS: After clinical implementation of the POET regimen almost half of the possible candidates with IE received oral step-down antibiotic therapy. Patients in the IV group had more serious risk factors for negative outcomes. At 6-month follow-up, there was a numerically but not statistically significant difference towards a lower incidence of the primary outcome, a lower incidence of all-cause mortality and a reduced length of stay in the PO group. Due to the observational design of the study, the lower mortality may to some extent reflect selection bias and unmeasured confounding. Clinical implementation of PO regimens seemed feasible and safe.

Light at night and cause-specific mortality risk in Mainland China: a nationwide observational study.

BACKGROUND: While epidemiological studies have found correlations between light at night (LAN) and health effects, none has so far investigated the impacts of LAN on population mortality yet. We aimed to estimate the relative risk for mortality from exposure to LAN in Mainland China. METHODS: This time-stratified case-crossover nationwide study used NPP-VIIRS to obtain daily LAN data of Mainland China between 2015 and 2019. The daily mortality data were obtained from the Disease Surveillance Point System in China. Conditional Poisson regression models were applied to examine the relative risk (RR) for mortality along daily LAN in each county, then meta-analysis was performed to combine the county-specific estimates at the national or regional level. RESULTS: A total of 579 counties with an average daily LAN of 4.39 (range: 1.02-35.46) were included in the main analysis. The overall RRs per 100 nW/cm2/sr increases in daily LAN were 1.08 (95%CI: 1.05-1.11) for all-cause mortality and 1.08 (95%CI: 1.05-1.11) for natural-cause mortality. A positive association between LAN and all natural cause-specific mortality was observed, of which the strongest effect was observed on mortality caused by neuron system disease (RR = 1.32, 95%CI: 1.14-1.52). The results were robust in both younger and old, as well as in males and females. The more pronounced effect of LAN was observed in median LAN-level regions. Combined with an exposure-response curve, our study suggests a non-linear association between LAN and mortality in China. CONCLUSIONS: Our study shows LAN is associated with mortality in China, particularly for neuron system disease-related mortality. These findings have important implications for public health policy establishment to minimize the health consequences of light pollution.

Hip and vertebral fracture risk after initiating antidiabetic drugs in Japanese elderly: a nationwide study.

INTRODUCTION: We aimed to clarify the risks of initiating antidiabetic drugs for fractures using a nationwide health insurance claims database (NDBJ). MATERIALS AND METHODS: Patients aged ≥ 65 years initiating antidiabetic drugs at the outpatient department were enrolled after a 180-day period without prescribed antidiabetic drugs and followed with during 2012-2018 using NDBJ. The adjusted hazard risks (HRs) of each antidiabetic drug (thiazolidine, alpha-glucosidase inhibitor, dipeptidyl peptidase-4 [DPP-4] inhibitor, sulfonylurea, glinide, and insulin) for fractures compared with biguanide were obtained adjusting for age, gender, polypharmacy, dementia, and the other antidiabetic drugs. RESULTS: The DPP-4 inhibitor was the most often prescribed antidiabetic drug followed by biguanide with prescribed proportions of 71.7% and 12.9%. A total of 4,304 hip fractures and 9,388 vertebral fractures were identified among the 966,700 outpatient participants. Compared with biguanide, insulin, alpha-glucosidase inhibitor, and DPP-4 inhibitor were related to increased hip fracture risks. Vertebral fracture risk was higher in outpatients prescribed with insulin, thiazolidine, and DPP-4 inhibitor compared with biguanide. Patients prescribed insulin for hip and vertebral fractures' adjusted HRs were 2.17 (95% CI 1.77-2.66) and 1.45 (95% CI 1.24-1.70), respectively. Those prescribed DPP-4 inhibitor for hip and vertebral fractures' adjusted HRs were 1.27 (95% CI 1.15-1.40) and 1.20 (95% CI 1.12-1.28), respectively. CONCLUSIONS: Initiating insulin increased the risk of not only hip fractures but also vertebral fractures. Patients initiating antidiabetic drugs had increased risks of hip and vertebral fractures compared with those initiating biguanide independently for age, gender, polypharmacy, and dementia in the Japanese elderly.

Association between pharmacotherapy and secondary hip fracture in a real-world setting: a nationwide database study.

INTRODUCTION: This study aimed to assess the association between pharmacotherapy and secondary hip fracture incidence. MATERIALS AND METHODS: The correlation between secondary hip fracture incidence and the presence, type, and medication possession ratio (MPR) of pharmacotherapy was investigated using medical insurance data acquired from the National Database of Health Insurance Claims and Specific Health Checkups of Japan. RESULTS: Data collected from female patients (n = 1,435,347) were analyzed. The 2-year secondary hip fracture incidence was 3.48% (n = 49,921). Secondary hip fracture was significantly more common in patients without medications (3.80%) than in those with medications (3.00%). Patients receiving selective estrogen receptor modulators (SERMs) had the lowest average age. The crude incidence of secondary hip fracture was the lowest in patients receiving SERMs (n = 2088 [2.52%]), followed by those taking bisphosphonates (n = 11,355 [2.88%]), denosumab (n = 1118 [2.90%]), no medications (n = 32,747 [3.80%]), and parathyroid hormone (PTH: n = 2163 [4.55%]), whereas the age-adjusted incidence was the lowest in patients administered denosumab (2.27%), followed by those taking bisphosphonates (2.47%), SERMs (2.55%), PTH (3.67%), and no medications (3.80%). The mean MPR was the highest in patients taking denosumab (64.9%), followed by those receiving bisphosphonates (58.7%), SERMs (58.2%), and PTH (40.6%) in the no hip fracture group. CONCLUSION: Secondary hip fractures were less likely to occur with medication versus no medication. Differences in the crude incidence of secondary hip fracture based on medications usage might be attributed to background characteristics.

Feeding practice during infancy is associated with attention-deficit/hyperactivity disorder and autism spectrum disorder: a population-based study in South Korea.

Attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are representative neurodevelopmental disorders. Using a nationwide database, we aimed to investigate whether feeding practices in infancy (breastfeeding and the timing of supplementary food introduction) could impact ADHD or ASD development. We evaluated 1,173,448 children aged 4-6 months who were included in the National Screening Program for Infants and Children (NHSPIC) between 2008 and 2014. We observed individuals until 6-7 years of age. Data on feeding type (milk feeding: exclusive breastfeeding [EBF], partial breastfeeding [PBF], exclusive formula feeding [EFF] at 4-6 months of age; supplementary food introduction: < 6 or > 6 months of age) were obtained from the NHSPIC, and diagnoses were based on the International Classification of Diseases, Tenth Revision. In a generalized linear model, children who received EBF had significantly lower incidence of both ADHD (odds ratio [OR]: 0.77, 95% confidence interval [CI]: 0.72-0.82) and ASD (OR: 0.64, 95% CI: 0.60-0.67) than that of children who received EFF. PBF also had a significant protective effect on both ADHD (0.91; 0.85-0.98), and ASD (0.89; 0.83-0.95). The timing of supplementary food introduction was not associated with either ADHD or ASD, although there was an increased risk of ASD in the EFF infants who had supplementary food introduced at > 6 months of age.  Conclusion: Our study strengthens and supports the beneficial effect of breastfeeding on neurodevelopmental disorders in children. Breastfeeding should be encouraged and recommended to promote desirable neurodevelopmental outcomes. What is Known: • Breastfeeding is beneficial for the overall health of children, including neurodevelopmental outcomes and cognitive functions. What is New: • Breastfeeding, especially exclusive breastfeeding, was protective against neurodevelopmental disorders. • The effect of the timing of supplementary food introduction was limited.

Temporal trend and factors associated with post-endoscopic retrograde cholangiopancreatography pancreatitis in children in the USA: a nationwide, retrospective cohort study.

Pancreatitis is the most common adverse event following endoscopic retrograde cholangiopancreatography (ERCP). Meanwhile, the national temporal trend of post-ERCP pancreatitis (PEP) in children remains to be reported. The purpose of this study is to investigate the temporal trend and factors associated with PEP in children. We conducted a nationwide study using data from the National Inpatient Sample database during 2008-2017 and included all patients aged ≤ 18 years who underwent ERCP. The primary outcomes were temporal trends and factors associated with PEP. The secondary outcomes were in-hospital mortality, total charges (TC), and total length of stay (LOS). A total of 45,268 hospitalized pediatric patients who underwent ERCP were analyzed; of whom, 2043 (4.5%) were diagnosed with PEP. The prevalence of PEP decreased from 5.0% in 2008 to 4.6% in 2017 (P = 0.0002). In multivariable logistic analysis, adjusted risk factors of PEP were hospitals located in the West (aOR 2.09, 95% CI 1.36-3.20; P < .0001), bile duct stent insertion (aOR 1.49, 95% CI, 1.08-2.05; P = 0.0040), and end-stage renal disease (aOR 8.05, 95% CI 1.66-39.16; P = 0.0098). Adjusted protective factors of PEP were increasing age (aOR 0.95, 95% CI 0.92-0.98; P = 0.0014) and hospitals located in the South (aOR 0.53, 95% CI 0.30-0.94; P < .0001). In-hospital mortality, TC, and LOS were higher in patients with PEP than those without PEP. CONCLUSION: This study shows a decreasing national trend over time and identifies multiple protective and risk factors for pediatric PEP. Endoscopists can use the insights from this study to evaluate relevant factors before performing ERCP in children to prevent PEP and reduce the medical-care burden. WHAT IS KNOWN: • Although ERCP has become indispensable procedure in children as they are in adults, education and training programs for ERCP in children are underdeveloped in many countries. • PEP is the most common and most serious adverse event following ERCP. Research on PEP in adults showed rising hospital admission and mortality rates associated with PEP in the USA. WHAT IS NEW: • The national temporal trend of PEP among pediatric patients in the USA was decreasing from 2008 to 2017. • Older age was a protective factor for PEP in children, while end-stage renal disease and stent insertion into the bile duct were risk factors.

Strong social disparities in access to IVF/ICSI despite free cost of treatment: a French population-based nationwide cohort study.

BACKGROUND: Access to IVF/ICSI is facilitated when the financial barrier is removed. In a national context where in vitro fertilisation (IVF)/intracytoplasmic sperm Injection (ICSI) treatment is cost-free, how many women do not access IVF/ICSI and what are the factors associated with non-access? METHODS: Using French national health insurance databases, the cohort included 20,240 women aged 18-43 years living in France who underwent unsuccessful treatment (no pregnancy) with clomiphene citrate (CC) and/or gonadotropins with treatment started between January and August 2016. The outcome measure was non-access to IVF/ICSI during the 24-month following start of infertility care. Factors associated with non-access to IVF/ICSI were explored using mixed effects logistic regression. RESULTS: In the cohort, 65.4% of women did not access IVF/ICSI. In multivariable analysis, non-access to IVF/ICSI was higher in younger women (18-25 years: (OR 2.17, 95% CI: 1.85-2.54) and in older women (40-43 years: (OR=3.60, 95% CI: 3.25-3.98)). Non-access was higher among women below the poverty line (OR=3.76, 95% CI: 3.34-4.23) and showed a significant upward trend with increasing deprivation of place of residence. Distance to the nearest fertility centre was not significantly associated with non-access to IVF/ICSI. CONCLUSIONS: In a national context of cost-free ART treatment, a large proportion of women did not access treatment, with a strong social gradient that raises important issues. We need to understand the underlying social mechanisms to develop an efficient and equitable health policy regarding infertility care.

Impact of the early phase of the COVID-19 pandemic on the use of mental health services in South Korea: a nationwide, health insurance data-based study.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic has profoundly affected the utilization of mental health services. Existing evidence investigating this issue at the nationwide level is lacking, and it is uncertain whether the effects of the COVID-19 pandemic on the use of psychiatric services differs based on psychiatric diagnosis. METHODS: Data from the claims database between October 2015 and August 2020 was obtained from the Health Insurance Review and Assessment agency in South Korea. Based on the main diagnostic codes, psychiatric patients were identified and categorized into diagnostic groups (anxiety disorders, bipolar and related disorders, depressive disorders, and schizophrenia spectrum disorders). We calculated the number of psychiatric inpatients and outpatients and the medication adherence of patients for each month. We compared the actual and predicted values of outcomes during the COVID-19 pandemic and performed interrupted time-series analyses to test the statistical significance of the impact of the pandemic. RESULTS: During the COVID-19 pandemic, the number of inpatients and admissions to psychiatric hospitals decreased for bipolar and related disorders and depressive disorders. In addition, the number of patients admitted to psychiatric hospitals for schizophrenia spectrum disorders decreased. The number of psychiatric outpatients showed no significant change in all diagnostic groups. Increased medication adherence was observed for depressive, schizophrenia spectrum, and bipolar and related disorders. CONCLUSIONS: In the early phase of the COVID-19 pandemic, there was a trend of a decreasing number of psychiatric inpatients and increasing medication adherence; however, the number of psychiatric outpatients remained unaltered.

Socioeconomic Disparities in the Association Between All-Cause Mortality and Health Check-Up Participation Among Healthy Middle-Aged Workers: A Nationwide Study.

BACKGROUND: This study assessed the relationship between non-participation in health check-ups and all-cause mortality and morbidity, considering socioeconomic status. METHODS: Healthy, middle-aged (35-54 years) working individuals who maintained either self-employed or employee status from 2006-2010 were recruited in this retrospective cohort study from the National Health Insurance Service in Korea. Health check-up participation was calculated as the sum of the number of health check-ups in 2007-2008 and 2009-2010. Adjusted hazard ratio (HR) and 95% confidence interval (CI) of all-cause mortality were estimated for each gender using multivariable Cox proportional hazard models, adjusting for age, income, residential area, and employment status. Interaction of non-participation in health check-ups and employment status on the risk of all-cause mortality was further analyzed. RESULTS: Among 4,267,243 individuals with a median 12-year follow-up (median age, 44; men, 74.43%), 89,030 (2.09%) died. The proportion (number) of deaths of individuals with no, one-time, and two-time participation in health check-ups was 3.53% (n = 47,496), 1.66% (n = 13,835), and 1.33% (n = 27,699), respectively. The association between health check-up participation and all-cause mortality showed a reverse J-shaped curve with the highest adjusted HR (95% CI) of 1.575 (1.541-1.611) and 1.718 (1.628-1.813) for men and women who did not attend any health check-ups, respectively. According to the interaction analysis, both genders showed significant additive and multiplicative interaction, with more pronounced additive interaction among women who did not attend health check-ups (relative excess risk due to interaction, 1.014 [0.871-1.158]). CONCLUSION: Our study highlights the significant reverse J-shaped association between health check-up participation and all-cause mortality. A pronounced association was found among self-employed individuals, regardless of gender.

National survey of abnormal uterine bleeding according to the FIGO classification in Japan.

AIM: To investigate the status of abnormal uterine bleeding (AUB) in Japan using the International Federation of Gynecology and Obstetrics (FIGO) classification (AUB system 1 and 2; PALM-COEIN) and to clarify the relationship between AUB symptoms and the diseases causing AUB. METHODS: In a nationwide study, we enrolled first-time patients who visited target facilities during two consecutive weeks from December 1, 2019 to January 31, 2020. The FIGO classification was used to investigate patients with symptoms and causative diseases of AUB. Based on the proportion of patients in the nationwide study, 373 cases were included in the detailed survey. Survey items included symptoms of AUB according to AUB system 1, examination details, and causative diseases according to the PALM-COEIN classification. RESULTS: Within the study period, we encountered 61 740 first-time patients, of which 8081 (13.1%) were diagnosed with AUB. Among them, 39.9% had abnormal menstrual cycles and 56.9% had abnormal menstrual bleeding. In the survey, PALM had the highest percentage of AUB-L and COEIN had the highest percentage of AUB-O. Correspondence analysis showed that COEIN was strongly associated with abnormal menstrual cycles and PALM with abnormal menstrual bleeding. CONCLUSION: We conducted the first nationwide survey of AUB in Japan. The FIGO classification was a useful tool for the diagnosis of AUB, with a strong correlation between symptoms of AUB by AUB system 1 and the causative disease of AUB by PALM-COEIN. Conversely, a high percentage of AUB-N and AUB-E suggests that AUB system 1 and PALM-COEIN are ambiguous as diagnostic tools.

Incidence and risk of stroke in Korean patients with congenital heart disease.

OBJECTIVES: The incidence and risk of ischemic stroke (IS) and hemorrhagic stroke (HS) in Korean patients with CHD have not been reported, therefore, we aimed to investigate this. MATERIALS AND METHODS: Participants were selected from the Korean National Health Insurance Service benefit records from 2006-2017. Cases were extracted using diagnosis codes related to CHD. Controls without CHD were selected through age- and sex-matched random sampling at a 1:10 ratio. RESULTS: The case and control groups included 232,203 and 3,024,633 participants, respectively. The median (interquartile range) follow-up period was 7.28 (3.59-8.73) years. The incidence rates of IS and HS per 100,000 person-years were much higher in cases than in controls (IS: 135 vs. 47; HS: 41.7 vs. 24.9). After adjusting for confounders, CHD was a risk factor for IS and HS (subdistribution HR; 1.96 and 1.71, respectively). In patients with CHD, the following risk factors were identified: diabetes, heart failure, and atrial fibrillation for any stroke; hypertension, atrial septal defects, and use of antiplatelet agents for IS only; and coronary artery bypass graft surgery for HS only. CONCLUSIONS: Korean patients with CHD have a high risk of stroke. A personalized preventive approach is needed to reduce the incidence of stroke in this population.

Comparison of survival rates between total knee arthroplasty after a previous anterior cruciate ligament reconstruction and primary total knee arthroplasty via propensity score matching.

INTRODUCTION: Although the survival rate of total knee arthroplasty (TKA) in patients treated with anterior cruciate ligament reconstruction (ACLR) is not as favorable as that in patients treated with primary TKA without ligament reconstruction, the exact survival rates and complications associated with these procedures are still controversial. Therefore, the purpose of the current study was to compare the revision rates of TKA in patients with knee osteoarthritis (OA) with a previous ACLR and those of patients with primary TKA with no history of knee surgery by using propensity score matching analysis. MATERIALS AND METHODS: A list of patients who underwent TKA from January 1, 2008 to May 31, 2019 was obtained from the Korean National Health Insurance database. Among these, 460 patients underwent TKA in a knee with a previous ACLR and 569,766 patients who underwent primary TKA due to degenerative OA. We performed propensity scoring matching to compare the revision rates including septic revision due to prosthetic joint infection after TKA and perioperative complication rates within 90 days after revision TKA between the two groups. RESULTS: Matched patients were assigned to one of the two groups (group A: 2,201 patients who underwent TKA due to primary OA, group B: 448 patients who underwent TKA in a knee with a previous ACLR) based on the propensity score. The total number of revisions per 1000 person-years was significantly higher in group B than in group A (10.16 vs 4.66, respectively). Group B showed a higher risk of revision than group A at 10 years post-TKA (hazard ratio: 2.49, 95% confidence interval: 1.30-4.77). However, group B showed a similar risk of septic revision as group A (p = 0.44). Perioperative complications within 90 days after TKA showed no significant differences between the groups. CONCLUSIONS: Surgeons should be aware of the relatively higher revision rate of TKA in patients who had previously undergone an ACLR compared to that in patients who underwent primary TKA.

A Nationwide Plasmidome Surveillance in Thailand Reveals a Limited Variety of New Delhi Metallo-ß-Lactamase-Producing Carbapenem-Resistant Enterobacteriaceae Clones and Spreading Plasmids.

Despite frequent identification of plasmids carrying carbapenemase genes, the transfer of plasmids carrying carbapenemase genes is not well recognized in clinical settings because of technical limitations. To investigate the detailed mechanisms of the spread of carbapenem-resistant Enterobacteriaceae (CRE), we performed multifaceted genomic surveillance of CRE isolates in Thailand and analyzed their plasmidome. We analyzed 371 Enterobacteriaceae isolates carrying blaNDM-1 and 114 Enterobacteriaceae isolates carrying blaNDM-5 obtained from clinical samples of 473 patients in 11 representative hospitals located in six provinces in Thailand between 2012 and 2017. The complete structures of plasmids carrying blaNDM and chromosomal phylogeny were determined by combining Southern blotting hybridization analysis and our previously performed whole-genome short-read sequencing data. Dissemination of the blaNDM-5 gene among the Enterobacteriaceae isolates in Thailand was mainly owing to the nationwide clonal spread of Escherichia coli ST410 and regional clonal spreads of Escherichia coli ST361 and ST405. Analysis of blaNDM-1-carrying isolates revealed nationwide dissemination of two specific plasmids and nationwide clonal dissemination of Klebsiella pneumoniae ST16 accompanied with regional disseminations of three distinctive K. pneumoniae clones (ST231, ST14, and ST147) with different plasmids. Dissemination of CRE carrying blaNDM in Thailand is mainly based on nationwide clonal expansions of E. coli ST410 carrying blaNDM-5 and K. pneumoniae ST16 carrying blaNDM-1, nationwide dissemination of two distinctive plasmids carrying blaNDM-1, and accumulation of clonal expansions in regional areas. Although the overuse of antibiotics can promote CRE dissemination, the limited variety of transmitters highlights the importance of preventing horizontal dissemination among patients.

Guideline adherence by physicians for management of glucocorticoid-induced osteoporosis in Japan: a nationwide health insurance claims database study.

Risk of fracture due to glucocorticoid-induced osteoporosis (GIO) can be reduced by anti-osteoporosis (OP) medications. The proportion of patients on long-term glucocorticoid therapy who received anti-OP medications according to the GIO management guidelines has increased in recent years, but is still suboptimal. INTRODUCTION: Adherence of physicians to guidelines for glucocorticoid (GC)-induced osteoporosis (GIO) management is currently unclear. This study aimed to clarify the state of guideline adherence by physicians in Japan and identify factors associated with guideline adherence using a nationwide health insurance claims database (NDBJ). METHODS: Patients aged ≥ 50 years who were prescribed GC for ≥ 90 days after 180 days without a GC prescription and who were followed up for osteoporosis (OP) management for the subsequent 360 days during the period spanning 2012-2018 were selected from the NDBJ. Guideline adherence was evaluated with the proportion of patients who received OP management as recommended by the Japanese guidelines. Information on previous vertebral and hip fractures, dementia, and polypharmacy was obtained. Factors associated with OP management were evaluated by logistic regression analysis. RESULTS: A total of 512,296 patients were considered to be at high risk of fracture according to the guidelines. Proportions of patients receiving OP management (BMD testing or anti-OP medications) have increased in recent years. In 2017, 33.7% of men and 55.3% of women received OP management in the initial 90 days of GC therapy. Female sex, previous anti-OP medications, polypharmacy, and higher GC dose were significantly associated with receiving OP management, while dementia showed an inverse association. A prior history of hip fracture, a strong risk factor for future fracture, was not significantly associated with receiving OP management. CONCLUSIONS: Although guideline adherence by physicians has increased in recent years, it remains suboptimal. Further efforts to improve guideline adherence are necessary. TRIAL REGISTRATION NUMBER: The present study is not registered.

Health care burden and mortality of acute on chronic liver failure in Thailand: a nationwide population-based cohort study.

BACKGROUND: Accurate population-based data are required concerning the rate, economic impact, and long-term outcome from acute on chronic liver failures (ACLF) in hospitalized patients with cirrhosis. We aimed to discover time trends for the epidemiology, economic burden, and mortality of ACLF in Thailand. METHODS: We conducted a nationwide, population-based, cohort study which involved all hospitalized patients with cirrhosis in Thailand during the period between 2009 and 2013, with data from the National Health Security Office. ACLF was defined by two or more extrahepatic organ failures in patients with cirrhosis. Primary outcomes were trends in hospitalizations, hospital costs, together with inpatient mortality. RESULTS: The number of ACLF hospitalizations in Thailand doubled between 3185 in 2009 and 7666 in 2013. The average cost of each ACLF hospitalization was 3.5-fold higher than for cirrhosis ($ 1893 versus $ 519). The hospital is paid using a diagnosis-related group (DRG) payment system that is only 15% of the average treatment costs ($ 286 from $ 1893). The in-hospital fatality rate was 51% for ACLF while the additional fatality rate was 85% up to 1 year. The ACLF organ failure trends indicated sepsis with septic shock and renal failure as the majority proportion. Age, the number and types of organ failure and male sex were predictors of ACLF death. CONCLUSIONS AND RELEVANCE: Cirrhosis and ACLF both represent substantial and increasing health and economic burdens for Thailand. These data can assist national health care policy stakeholders to target high-risk patients with cirrhosis for care.

Vaginal estrogen and association with dementia: A nationwide population-based study.

INTRODUCTION: Use of systemic hormone therapy has been positively associated with development of dementia. Little is known about the dose-dependent effect of vaginal estradiol on dementia risk. METHODS: We assessed associations between cumulative dose of vaginal estradiol tablets and dementia in a case-control study nested in a nationwide Danish cohort of women aged 50 to 60 years at study initiation, who did not use systemic hormone therapy. Each case was age-matched to 10 female controls. RESULTS: A total of 4574 dementia cases were matched to 45,740 controls. Cumulative use of vaginal estradiol tablets was not associated with all-cause dementia; adjusted hazard ratio 1.02 (95% confidence interval [CI] 0.89-1.18) for low dose (< 750 mcg), 1.07 (0.94-1.21) for medium dose (750-2000 mcg), and 0.93 (0.84-1.03) for high dose (> 2000 mcg). Similarly, Alzheimer's disease (AD) only was not associated with vaginal estradiol. DISCUSSION: Exposure to vaginal estradiol tablets was not associated with all-cause dementia or AD only.

Association Between Nonsteroidal Antiinflammatory Drug Use and Adverse Clinical Outcomes Among Adults Hospitalized With Coronavirus 2019 in South Korea: A Nationwide Study.

BACKGROUND: Nonsteroidal antiinflammatory drugs (NSAIDs) may exacerbate coronavirus disease 2019 (COVID-19) and worsen associated outcomes by upregulating the enzyme that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to in order to enter cells. METHODS: We conducted a cohort study using South Korea's nationwide healthcare database, which contains data for all individuals who received a COVID-19 test (n = 69 793) as of 8 April 2020. We identified adults hospitalized with COVID-19, where cohort entry was the date of hospitalization. NSAID users were those prescribed NSAIDs in the 7 days before and including cohort entry, and nonusers were those not prescribed NSAIDs during this period. Our primary outcome was a composite of in-hospital death, intensive care unit admission, mechanical ventilation use, and sepsis; our secondary outcomes were cardiovascular complications and acute renal failure. We conducted logistic regression analysis to estimate odds ratio (OR) with 95% confidence intervals (CIs) using inverse probability of treatment weighting to minimize confounding. RESULTS: Of 1824 adults hospitalized with COVID-19 (mean age, 49.0 years; female, 59%), 354 were NSAID users and 1470 were nonusers. Compared with nonuse, NSAID use was associated with increased risks of the primary composite outcome (OR, 1.54; 95% CI, 1.13-2.11) but insignificantly associated with cardiovascular complications (OR, 1.54; 95% CI, 0.96-2.48) or acute renal failure (OR, 1.45; 95% CI, 0.49-4.14). CONCLUSIONS: While awaiting the results of confirmatory studies, we suggest NSAIDs be used with caution for COVID-19 patients as the harms associated with their use may outweigh their benefits.

Clinical practice and outcome of radiotherapy for advanced esophageal squamous cell carcinoma between 2002 and 2018 in China: the multi-center 3JECROG Survey.

PURPOSE: To determine the survival and prognostic factors of esophageal squamous cell carcinoma (ESCC) patients undergoing radical (chemo)radiotherapy in the era of three-dimensional conformal radiotherapy (3DCRT) and intensity modulated radiotherapy (IMRT) in China. MATERIAL AND METHODS: The Jing-Jin-Ji Esophageal and Esophagogastric Cancer Radiotherapy Oncology Group (3JECROG) conducted the first nationwide survey of nine institutions. Detailed information was accumulated on 5185 patients with ESCC who received definitive 3DCRT/IMRT between 2002 and 2018. Relevant prognostic factors were evaluated to assess their influence on overall and progression-free survivals. RESULTS: After a median follow-up time of 47.0 (0.9-157.4) months, the 1-year, 2-year, 3-year and 5-year overall survival rates of the whole group were 69.8%, 46.6%, 37.9% and 30.1%. The 1-year, 2-year, 3-year, and 5-year progression-free survival rates were 54.1%, 36.6%, 30.5% and 24.9%. Multivariate analysis demonstrated that sex, clinical stage, treatment modality and radiation dose were prognostic factors for OS. The survival of patients who received concurrent chemoradiotherapy (CCRT) was better than that of patients who received radiotherapy alone or sequential chemoradiotherapy. Patients receiving adjuvant chemotherapy after CCRT had a better OS than patients receiving CCRT alone. Patients receiving higher radiation dose had a better OS than those patients receiving low-dose radiotherapy. CONCLUSIONS: The survival of ESCC patients undergoing radical (chemo)radiotherapy was relatively satisfactory in the era of 3DCRTand IMRT. As the largest-scale multicenter research on esophageal cancer radiotherapy conducted in China, this study establishes national benchmarks and helps to provide references for subsequent related researches.
